Question

mean proportional number of 32, 18 is​

Answer 1

$\huge{\boxed{\boxed {\pink{\mathfrak{Solution:}}}}}$

Mean proportional means a:b::b:c where b is common in both.

$\boxed {\blue {Product\:of\:means=Product\:of\:extremes}}$

Let x be mean proportion.

$\therefore {\bold{32:x::x:18}}$

$\implies Product\:of\:means=Product\:of\:extremes \\ \implies x \times x = 32 \times 18 \\ \implies x^2 = 576 \\\implies x = \sqrt{576} \\ \implies x =24$

$\boxed{\green {\therefore{Mean\: proportional\: number\: is \:24.}}}$
